Let's see what the 70 D sensor is going to be like, they are delaying it so long with respect to Nikon's D 7100 that hopefully it may mean a new tech sensor will be introduced with Canon's next camera which, according to rumors, should be just around the corner... that's why I'm waiting for it so eagerly. But I've no idea what this tech could be about, just shrinking the fab process from 500 nm to 250 or 180 or less is not enough to obtain considerably better DR, further innovation is mandatory. Could it be the use of something else instead of pure silicon for the CMOS (apart from Cu in back-end-of-line), like Intel did with its 45 nm process employing hafnium in their hi-k metal gate for a completely different purpose?

Well, I admit I'm ignorant in this respect, but I'm throwing this idea in with the hope that someone well-informed may contribute with some hint; as I said earlier, speculating is the most fun to me on Canon Rumors and learning from those technically skilled members here is the best part of it. I suspect that composite materials and composite nanostructures may represent the future of imaging sensors.

My 2 cents, large MP bodies appeal to landscape shooters so a smaller body is more appealing. Nikon made the same decision with the D800 series. Sports and photojournalist shooters need higher frame rates which is mutually exclusive from high megapixels. If Vanon has any sense, a high MP camera will be in a small body.

This is an interesting discussion...If this new medium format sized camera is not going in the 1DX type body then I suspect that it will be in the $4K price range? Seems to me that if they get much beyond that they have the same problem that they have now competing with Nikon's D800, which clearly gets better marks than does the 5D MK IIII am more interested in what this new sensor technology, as applied to a replacement for my 1DX will look like, be, and cost....I mean, how many fps does a wildlife or sports shooter need, 20? Or more?? I have seen DSLR technology come a long way in the last 10 years...and the current techology today, at the high end of the $$ scale, is pretty amazing...I guess it will be fun, if not EXPENSIVE, to see where it goes next.....we have seen what the latest lens costs are, $18K for the new Nikon 800mm and the 200-400 costing as much as the 600 II costs...oh well, I will be waiting....but I don't expect to see any replacement for the 1DX actually hit the streets before the end of 2015....thoughts??

There seems to be an awful lot of wishful thinking going on in this thread, with many hoping it will be in a 5D-type body - especially as that could indicate a more affordable price as compared to a 1D ?.

Personally I cannot see that happening. The 1D S makes more sense from where I am sitting. They make a flagship studio camera to go along with the flagship sport / high fps camera, and then remove certain features to eventually get down to a 5D Mark IV.

If they do call the new Megapixel camera the 1DS or the 1DXS what will they call the new 1DX in end-2014 early 2015?

AND IT NEEDS TO BE CHEAPER THAN THE 1DX OTHERWISE WE MAY AS WELL USE MEDIUM FORMAT DIGITAL

you obviously don't have a medium format! they are a pain in the ass to use, so far behind in technology. price isn't everything, i want it to do the best job it can, price isn't the most important factor for a big chunk of the market.

what i need as an advertising photographer is more speed, more iso and lots of megapixels. my p65+ has enough pixels, it just cant be used in many situations. if canon can release a decent high megapixel camera that can do iso 800 at 3-5 fps, they will own the high end of the market.

Releasing a 1-series big MP camera still wouldn't really solve the `problem' of enabling Canon to compete with the D800. $3000 & $7000-$10,000 are different brackets altogether. It depends how desperately Canon feels the need to do this. Maybe they don't. I'm guessing the 5D iv will have about 30MP, but that won't happen for 2 years or more surely.

And no way will Canon name the camera 1d-"excess". Canon is a conservative company and that would not be conservative marketing.

Definitely one thing that is happening, and will continue to happen, in the camera market is more differentiation in FF options. In 2003 Canon had only 1, in 2005 2, currently 3 (not counting the 1DC). Clearly there will be more, probably an RX1-like camera, and more differentiation in 1 & 5 series bodies. Whether this will suck one option out of the APS-C lineup, who knows, I doubt it somehow.

Now I'll be happy when I see 6D Mark II with the same sensor technology as this future 1DS albeit at a lower MP, and 7D-like AF coverage with at least 9 cross-type current, 6D center point performance and priced just like 6D during initial intro. I think for most of us, that's the real deal unless you're rich or you're earning money from photography.
